Quaternary ammonium compounds in hypersensitivity reactions [PDF]
Quaternary ammonium compounds (QAC) are commonly used disinfectants, antiseptics, preservatives, and detergents due to their antibacterial property and represent the first used biocides before phenolic or nitrogen products.

Food and bile micelle binding of quaternary ammonium compounds [PDF]
Background and Purpose: Physiologically-based biopharmaceutics modeling (PBBM) has been widely used to predict the oral absorption of drugs. However, the prediction of food effects on oral drug absorption is still challenging, especially for negative ...

Quaternary Ammonium Compounds as Candidate Photoprotective Compounds in Reef-Building Corals
Quaternary ammonium compounds (QACs) – e.g., betaines – have a chemical structure related to that of the tertiary sulfonium compounds (TSCs) – e.g., dimethylsulfoniopropionate – explaining why these two classes of coral metabolites are often studied and ...

Development of novel effective agents from 1H-indolylammonium trifluoroacetates effective against conditionally pathogenic microorganisms [PDF]
Introduction: The problem of antibiotic resistance of microorganisms is becoming more urgent in the twenty-first century. More and more pathogenic microbes are becoming resistant to two or more antibiotics. This problem has become worse into the COVID-19
